Climate action festival class 1

 Make a plan for your display : Create a strategy to invite people to come to your booth and make a plan to engage the interest of your audience

TOPICS: 

1. MEASURING CO2 :   take CO2 levels in different school rooms show pics of result.  

Make a poster describing the CO2 levels in different areas of the school or home or in any other places of your choosing.  Also, include the following information in your poster

4.  historical CO2 levels NASA and NOAA data shows changes in CO2 over time. Make a poster of Climate change & a physical creative display of the earth & CO2 & using props  

5.  Performance options: 

Do some busking at the festival:  

Or help run a button making station or...your choice

6.  Co-design a sustainable future: Be an artist for the festival WHAT ARE BUILDINGS THAT USE LESS ENERGY: SUSTAINABLE ARCHITECTURE

CREATE A DREAM FOR SUSTAINABLE LIVING

TOPICS can include  transportation , living in your house, work, shopping , gathering, recreation 

7.  Create sustainability buttons for the Clean Air festival.  Use the button maker from the library.

8.  Make a poster on the climate change impacts of DATA CENTRES

8.  SUSTAINABLE TRANSPORTATION .  WHAT ARE ALL THE ALTERNATIVES FOR TRANSPORTATION?  

  Here are the Fusion and Fission notes 

I gave you a worksheet called 7.3 Nuclear Reactions, the answer key to that is here

There is also the Radioactive unit exam study guide  and Answer key 

Here is the powerpoint on the nuclear bomb

Solid Carbon Dioxide Lab: The Dry Ice Lab

 

Purpose: Observe the properties of carbon dioxide.  Discover what happens when carbon dioxide mixes with water. Record a neutralization reaction.  

Write an INTRODUCTION to your lab report summarizing the properities of CO2 .  Write this in paragraph form and include at least 5 properties of dry ice

Materials: Dry ice, universal indicator, sodium hydroxide, water.  Caution:  ice is -73 celsius and may cause skin damage if it is touched.  Sodium hydroxide is corrosive.  Universal indicator is poisonous.  Use appropriate eyewear. Wash hands with soap after the lab is over.

Safety precautions: write the safety precautions for this lab as reviewed in class

Procedure: Follow the procedure and write your observations:
Properties of carbon dioxide:  
1. Place a nugget of ice on the table and bat it around with your hands.  It'll start to slide around
2.  Place a nugget of ice on the table and put a coin on it.  Breathe on the coin.
3.  Place a nugget of ice in a puddle of water
4.  Rate of Reaction: Put ice in a flask of cold water.  Now use hot water.
5. Neutralization:  Put on your goggles: place a dropperful of sodium hydroxide in a flask of water and another dropperful of universal indicator. Drop a nugget of ice in the water.  Observe the reaction.

Conclusions:  write down your conclusions on the properties of Carbon Dioxide. Include at least 10 things you observed and learned about DRY ICE INCLUDING THE neutralization reaction.  include all equations that were demonstrated

Evaluation

write this as a group assignment dividing up the work.  Write it by hand , include drawings.  Make a pie graph indicating % done by each investigator.  Use FULL NAMES. If you need an alternative to handwriting for any reason please talk to me to arrange a different way to demonstrate your knowledge

35- 40 marks for a complete and thorough write up with DRAWINGS, AND MAKE A CARTOON OF THE PROCEDURE AND OBSERVATIONS. Write in paragraph form in ink and use colour

20-34. A really good write up with no colour no ink but the CONTENT OF THE MATERIAL is very well done

0-20. this work is incomplete

Universal Indicator Rainbows

 We used universal indicator, a known acid and a known base to create as many pHs as possible. 

spot plate lab

 Do an experiment with some unknown chemicals.  Write up your experiment in a lab report. Use your knowledge from the Acids and Bases notes to deduce what happened during our little magic trick.  Write up your experiment.  You will include data from  spot plate labs

LAB REPORT

Purpose:  To do some experiments and deduce how the teacher did the magic trick

procedure:  

1.  Observe the magic trick: describe it in great detail in point form

2.  Devise an experiment with the spot plates to determine as much information as you can about the two liquids:  "white wine" and "red wine".  Describe your experiment in point form.

3.  Write your observations.

RESULTS:

DRAW A PICTURE to show your results.  

CONCLUSION

Tell me your best hypothesis on how I might have done that magic trick. Use evidence from your experiment. Conclusion=1 mark.  Evidence=10 marks. 

Introduction to chemistry

    

An analogy for Atoms, Compounds and Formula, drawn by SN This video is the first in the series for beginner Chemistry. In this video, I use the analogy of the atom as units very much like "lego bricks". This analogy was first used by researchers in MIT.
